I think the traditional "heavy item" is a breeze-block. We'll be able
to find a couple of those easy enough.

As far back as I can remember there has always been a block of post it notes next to the phone, just a few steps from the message board.

A device attached to the pass that emits a loud and annoying beep every
twenty seconds or so.
This will not be a problem in an unattended car but will remind the driver
to return it before s/he leaves the yard. The sound is disabled when the
pass is hung on the appropriate hook by the notice board. A nice project
for someone...
I am sure that someone will manage to shoehorn an Arduino into the plan
somewhere along the line... :-)

I can vouch for these. Someone stashed one at a place I once worked.
Took a week to locate. They were up ladders, in ceiling tiles,
everything!
